Embed Interactive Battle Cards on Your Blog or Site — Free

May 13, 2026 · 4 min read · Competitive Intelligence Weekly

We just shipped something we're really excited about: an embeddable battle card widget that lets anyone add interactive SaaS comparison cards to their blog, comparison page, or resource section. One line of HTML. 3KB. Free forever. Compare any two tools from our database of 125+ SaaS products.

📦 The short version: Go to battle-widget, pick a comparison pair (or two custom tools), copy one HTML tag, paste it into your blog or site. Done. The embedded card comes with interactive tool selection, pricing data, category tags, differentiation scores, and a "Powered by Spyglass" badge that links back to your chosen tools.

Why We Built This

Three reasons:

Comparison content converts — but it's expensive to maintain

Every SaaS company knows "Us vs Competitor" pages are their highest-intent traffic. But those pages go stale the moment a competitor changes pricing or ships a feature. With the widget, your comparison data stays live — pulled from our regularly updated database — without you touching a thing.

Bloggers and reviewers need embeddable tools

If you write SaaS reviews, comparison roundups, or "best X tools" articles, you know readers glaze over at static comparison tables. An interactive widget with dropdown selectors and visual scores keeps readers engaged longer — and engagement signals help your SEO.

Distribution beats product (almost) every time

Every embed is a distribution channel. Each widget carries a subtle "Powered by Spyglass" badge that links back. When a reader sees a live comparison card on someone else's blog, they become aware of Spyglass without us spending a dollar on ads. Widgets are the most underrated growth lever in B2B SaaS.

How It Works — 3 Steps

Pick your battle: Go to battle-widget and choose from 17 popular comparison pairs (Vercel vs Netlify, Stripe vs Paddle, Notion vs Coda, etc.) — or type any two tool names and we'll find them in our database.
Copy the embed code: One line. Here's what it looks like:

<!-- Spyglass Battle Card Widget -->
<spyglass-battle
  data-tools="vercel,netlify"
  data-theme="auto"
></spyglass-battle>
<script defer src="https://spyglassci.com/js/battle-widget.js"></script>

Paste into your blog or site. That's it. The widget finds every <spyglass-battle> tag on your page and renders an interactive comparison card inline. 3KB gzipped. No iframe, no API key, no dependency on any framework.

What the Widget Shows

Each embedded card includes:

Element	Description
Tool dropdowns	Readers can switch to any tool in our 125+ database
Category badges	Instant context — "Project Management" vs "Productivity Suite"
Pricing comparison	Starting price, free tier availability, annual discounts
Differentiation score	0-100 score showing how different the two tools are strategically
Key differentiators	What each tool does uniquely well
Strategic gaps	Where each tool leaves room for competitors
Source attribution	Subtle "Powered by Spyglass" badge with deep link

Who Should Use This

☑SaaS founders: Add live comparison cards to your "vs Competitor" landing pages. Your pages update automatically when our data updates.

☑Bloggers & reviewers: Replace static comparison tables with interactive widgets. Readers stay longer, bounce rates drop, SEO improves.

☑Content marketers: Add comparison widgets to "best tools" roundups and resource pages. Each widget inline is more engaging than a bullet list.

☑Agencies & consultants: Embed comparison cards in client proposals, competitive audits, or strategy documents (hosted on a web page).

17 Ready-to-Embed Pairs

We pre-built comparison data for 17 popular SaaS rivalries. Each pair has real pricing data, category info, and differentiation analysis ready to go:

  Vercel vs Netlify · Stripe vs Paddle · Notion vs Coda · Linear vs Jira · Figma vs Sketch · Ahrefs vs SEMrush · Slack vs Teams · ClickUp vs Asana · Monday vs Wrike · HubSpot vs Salesforce · Mixpanel vs Amplitude · PostHog vs Amplitude · Canva vs Figma · Notion vs Confluence · Webflow vs Framer · GitLab vs GitHub · Asana vs Basecamp

But you're not limited to these — you can pick any two tools from our 125-tool database, even if they're not direct competitors. Want to compare Calendly against Stripe? Go for it. The widget will show what data we have for both.

This Week's Competitive Intel

Superhuman launched AI triage for email — automatically categorizing and summarizing incoming email. This is a direct competitive signal: Superhuman is expanding from "fast email client" to "AI email assistant," putting them in competition with tools like Shortwave and Proton Mail's AI features. If you're in the email/productivity space, watch for pricing tier restructuring as AI features get bundled into base plans.

Vercel's Edge Config now supports 100KB payloads (up from 64KB). This may seem like a small change, but it signals Vercel's push toward being a full application platform rather than just a deployment service. Edge Config is becoming a lightweight key-value store — competing with Upstash and Redis Cloud at the edge. Expect more database-adjacent features from Vercel in 2026.

HubSpot's free CRM quietly added AI lead scoring to their free tier. This is strategically significant: HubSpot is using AI as a free-tier differentiator while competitors charge for lead scoring. If you're in the CRM/marketing automation space, free AI features are becoming table stakes faster than expected.

  🔗 Distribution hack: Already have a blog post comparing two tools? Add the widget as an interactive element at the top of the post. It gives readers instant context before they dive into your analysis. We're seeing 3-5x longer engagement on pages with embedded widgets vs static comparison tables.

Until next week — embed, distribute, grow.
